Overview
Advertising pixel that tracks page visits, sign-ups, and purchases, sending conversion data to Pinterest's US-based ad platform for retargeting and audience creation. Lower profile than Meta or Google advertising tags, which means it is frequently overlooked during governance audits despite collecting comparable browsing and conversion data. Enhanced Match functionality can transmit hashed personal data, which should be disclosed in the organisation's privacy notice.

Common mistakes
- 1Overlooking the Pinterest Tag during consent audits because it is less prominent than Meta or Google tags, resulting in it firing without valid consent
- 2Enabling Enhanced Match without assessing the privacy impact - it sends hashed email addresses to Pinterest for cross-device attribution
- 3Not implementing the Conversions API alongside the browser tag, leading to incomplete conversion data and redundant client-side tracking
- 4Failing to restrict event tracking to relevant conversion pages, causing unnecessary data collection across the entire site
- 5Not including Pinterest in the advertising consent category within the CMP, allowing it to fall through as an uncategorised tag
Compliance considerations
The Pinterest Tag sets first-party cookies (_pin_unauth, _pinterest_ct_ua) and transmits browsing and conversion data to Pinterest servers in the United States. Under GDPR, this requires explicit advertising consent before the tag fires. Pinterest is self-certified under the EU-US Data Privacy Framework, providing a transfer mechanism for EU-to-US data flows, but organisations should verify the current certification status. Enhanced Match functionality transmits hashed personal data and should be disclosed in the privacy notice. Organisations should ensure the Pinterest Tag is categorised under advertising consent in their CMP and blocked until explicit consent is granted.
